Corrections for recognizers

A processing device for recognizing a plurality of atoms of structured handwritten input, the processing device comprising:

• at least one processor;
• and
• a memory connected to the at least one processor, the memory further comprising:
• instructions for receiving an input indicating a second plurality of atoms of the plurality of atoms corresponding to a portion of the structured handwritten input, at least some of the second plurality of atoms having been misrecognized as a symbol not being under a root structure,
• instructions for displaying a menu of possible recognition results based on the second plurality of atoms,
• instructions for receiving a selection of one of the possible recognition results as a correction hint,
• instructions for determining whether a first part of the second plurality of atoms, corresponding to the correction hint, is under the root structure and whether a second part of the second plurality of atoms, corresponding to the correction hint, is not under the root structure;
• and
• instructions for recognizing the plurality of atoms, in conformance with the second correction hint, as including at least one symbol under the root structure, corresponding to the first part of the second plurality of atoms and the second part of the second plurality of atoms, when the first part of the second plurality of atoms is determined to be under the root structure and the second part of the second plurality of atoms is determined to be not under the root structure.

A tangible machine-readable medium having instructions for at least one processor recorded thereon, the instructions comprising:

• instructions for receiving input indicating at least one atom of a plurality of atoms of handwritten input, the at least one atom having been misrecognized by a recognizer;
• instructions for displaying a menu of possible recognition results based on the at least one atom;
• instructions for receiving a selection of one of the possible recognition results as a correction hint;
• and
• instructions for leveraging the correction hint to produce a corrected recognition result, the instructions for leveraging the correction hint to produce a corrected recognition result further comprising at least one group of instructions selected from:
• a first group of instructions for linearly transforming the at least one atom corresponding to the correction hint such that the at least one atom is horizontally or vertically separate from other atoms of the plurality of atoms,
• a second group of instructions for leveraging the correction hint to correct an over-grouping error of a matrix when the second correction hint indicates that the at least one atom is to be in a single cell of a matrix, and
• a third group of instructions for recognizing the at least one atom as being under a root structure when the correction hint indicates that a first part of the at least one atom corresponding to the correction hint is under a root structure and a second part of the at least one atom corresponding to the correction hint is not under the root structure.
